General Spider Information

Did you know that spiders are arachnids? Arachnids is a Roman word for eight legged creature. They have two main body parts which are the cephalothorax and the abdomen. On their abdomen they have their spinnerets. Silk comes from the abdomen. That is how they make their egg sac. In their cephalothorax, it has it's eyes, and the glands. Also some of it's legs are connected to the cephalothorax.

Spiders are in a different group than insects. Also, spiders are invertebrates.
